Methods of manufacturing magnetic compositions of carbon modified chromium oxide

ABSTRACT

THIS INVENTION RELATES TO THE FORMATION OF FERROMAGNETIC CHROMIUM OXIDE COMPOSITIONS CONTAINING 59% TO 62% CHROMIUM AND 0.05% TO 0.90% CARBON COMBINED WITH OXYGEN, AND IN THE FORM OF FINELY DIVIDED PARTICLES OF TETRAGONAL CRYSTALLINE STRUCTURE. THE PROCESS OF FORMING CARBON MODIFIED FERROMAGNETIC CHROMIUM OXIDE CONSISTS OF MIXING A SOLUBLE CHROMIUM HALIDE COMPOUND WITH AN ORGANIC COMPLEXING AGENT, ASSOCIATING THE COMPLEX WITH ADDITIOANL CHROMIUM COMPOUND, AND THEN SUBJECTING THE MIXTURE TO HEAT AND PRESSURE DECOMPOSITION.
